NTP: Microwave News Article Archive (2004 - )

“Considering (a) the conflicting results of RF epidemiology studies and (b) the lack of generally accepted biophysical or molecular mechanisms through which RF could induce or promote neoplasia, data from animal bioassays will play a central role in ‘weight-of-the-evidence’ assessments of the possible health effects of RF exposure.” Abstract only. By IITRI’s David McCormick, who ran the exposures for the NTP–cell phone cancer study.

”A few days ago, I received an urgent warning from a longtime contact in Sweden. An industry associate had told him that the U.S. National Toxicology Program’s study on cell phone cancer risks was screwed up and essentially “useless.”

I was tempted to disregard it as nothing more than a corporate delusion. But the original source was said to be Maria Feychting, a professor at the Karolinska Institute and the vice chair of the International Commission on Non-Ionizing Radiation Protection (ICNIRP). She had cast doubt on the landmark $25 million NTP RF–animal study in a talk presented at the Royal Swedish Academy of Sciences —the institute that awards the Nobel prizes in physics and chemistry every year.

The National Toxicology Program (NTP) will release the “complete results” of its $25 million project on cell phone cancer risks early next year, according to a statement posted on its Web site yesterday.

“The complete results from all the rats and mice studies will be available for peer review and public comment by early 2018,” the NTP states. The animals were exposed to GSM or CDMA radiation for two years before they were sacrificed...

Narendra P. Singh, known to friends and colleagues simply as NP, died last December at the age of 69. When his family wrote to me with the news, Singh’s wife asked me not to publish a tribute or an obituary at that time. I honored her request, but now, after a decent interval, I break my silence, in part to make good on a promise and to settle some unfinished business.

Singh was a proud and honest man; he was also gentle and unassuming. “He cannot tell a lie, even a white lie,” Henry Lai, his long-time collaborator at the University of Washington in Seattle, told me years ago. Perhaps most of all, Singh was a meticulous experimentalist who believed in the power of science.

The National Toxicology Program (NTP) has changed course and will not —at least for the time being— publish its findings of increased DNA breaks among rats exposed to cell phone radiation as a stand-alone paper.

The DNA study, which is part of NTP’s landmark experiment showing that RF radiation can lead to tumors in the brains and hearts of laboratory animals, will now be incorporated in NTP’s Technical Report on the $25 million project, the NTP has told Microwave News.

The incidence of glioblastoma multiforme (GBM), the most virulent and deadly type of brain cancer, is going up in the U.K., while the incidence there of other types of malignant brain tumors are declining, according to some newly published raw data.

Take a look at the two plots below and the trends are immediately apparent.

Geoffrey Kabat offers a remarkably apt critique of his own writings with his answer to the question, “Do Cell Phones Cause Brain Cancer?”:

“The problem with research in this area is not that it is worthless but that all too frequently it is interpreted naively and uncritically and used for partisan rather than scientific purposes.”

That’s from his new book, Getting Risk Right. It may be the only thing he gets right in the whole book. Hard to say because after reading the chapter on cell phone radiation, we couldn’t slog on much further.

In May, the U.S. National Toxicology Program (NTP) announced that male rats exposed to cell phone radiation developed higher rates of cancer. Soon, the NTP will explain how that might have happened.

The same RF/microwave radiation that led male rats to develop brain tumors also caused DNA breaks in their brains. Female rats —which did not have significant elevated tumor counts— had fewer DNA breaks.

Also here. Mostly Michael Wyde’s talk with important comments by NTP Director Linda Birnbaum and Associate Director John Bucher. Birnbaum calls the link between RF and Schwannomas of the heart “unequivocally clear” (@43:20-minute mark). A few minutes later, she describes it as having a “beautiful dose-relationship.” Bucher talks about the continuity in the spectrum between hyperplasia and glioma.

Carroll outlined reasons for his skepticism over the cancer results, calling the $25 million NTP study “imperfect.” This prompted a response from Ron Melnick, who led the study’s design team before he retired in 2009. In an eight-point rebuttal, Melnick corrected what he called “numerous and misleading statements.” The full text of his letter is reprinted below.

Senior managers at the National Toxicology Program (NTP) released the preliminary results of their cell phone radiation study late last week. They were so concerned about the elevated rates of two types of cancer among exposed rats that they felt an immediate public alert was warranted. They considered it unwise to wait for the results to wend their way into a journal sometime next year. Not surprisingly, the NTP report generated worldwide media attention.

There were some startling reactions. Both the American Cancer Society (ACS) and Consumer Reports immediately shelved their long-held, wait-and-see positions. In a statement issued soon after the NTP’s press conference, Otis Brawley, ACS’ chief medical officer, called the NTP report “good science.” Consumer Reports said that the new study was “groundbreaking” and encouraged people to take simple precautions to limit their exposures.

This evening, the National Toxicology Program (NTP) released a draft of the report on its two-year cell phone cancer study. Linda Birnbaum, the director of the NIEHS, and John Bucher, the leader of the study, will present the report at a teleconference tomorrow, Friday. They are the director and associate director of the NTP, respectively. [Birnbaum did not...

The U.S. National Toxicology Program (NTP) is expected to issue a public announcement that cell phone radiation presents a cancer risk for humans. The move comes soon after its recently completed study showed statistically significant increases in cancer among rats that had been exposed to GSM or CDMA signals for two-years.

Discussions are currently underway among federal agencies on how to inform the public about the new findings. NTP senior managers believe that these results should be released as soon as possible because just about everyone is exposed to wireless radiation all the time and therefore everyone is potentially at risk.

Once again, power-frequency magnetic fields have been found to act as a cancer promoter.

Eighteen months ago an international team led by Elisabeth Cardis in Spain showed cancer promotion in workers exposed to chemicals and extremely low frequency (ELF) EMFs. Now an Italian team has found essentially the same promotional effect in animals exposed to ionizing radiation and ELF EMFs.

The new study, which was carried out at the Ramazzini Institute in Bologna, Italy, is part of the most ambitious EMF–animal project ever attempted.

NIEHS really doesn’t want to talk about it. Ten years into a $25+ million project to assess the cancer risk of wireless radiation in laboratory animals, the staff at the National Institute of Environmental Health Sciences remains tight-lipped and refuses to release project documents.

NIEHS has many reasons for keeping a low profile. The RF project, the most expensive in National Toxicology Program history, is years late and two-to-three times over budget. A more immediate concern is that it could force the institute into a position it would desperately prefer to avoid: Being at the center of the ever-contentious controversy over cell phone radiation and cancer.

The Washington Post's health section offers its take on the cell phone–tumor story today. In "Not Exactly a Ringing Endorsement," reporter John Donnelly presents a variety of opinions from DC area residents: "Everything is a risk. I'm a bodyguard. That's risky. You got to have a life. Cell phones don't scare me," said one. "It makes me nervous," said a pregnant 26-year-old, "I use the speakerphone as much as I can. I keep it away from my body. I try to use it very little."
